Helen H. Richardson/The Denver Post via Getty Images(CENTENNIAL, Colo.) -- Claire Davis, the 17-year-old Colorado girl critically injured in the shooting at her high school, is in a coma, her family said Sunday night.

In a statement posted on the Littleton Adventist Hospital Facebook page, the family said: "Claire remains in critical condition. She is stable, but is in a coma."

Davis, a senior at Arapahoe High School, was critically wounded when she was shot at point-blank range by Karl Pierson on Friday. She suffered severe head trauma in the shooting, according to the hospital.

Pierson, 18, was armed with a shotgun and a machete, and had Molotov cocktails in his backpack, police said.

According to police, Pierson was seeking "revenge" on the school's debate team instructor, Tracy Murphy, who had dropped him from the team.

The girl's family said she has gotten good care and asked for privacy.

"The first responders got Claire to the right place, at the right time, and the doctors and hospital staff are doing a wonderful job taking care of her," the statement said. "We appreciate your continued good thoughts and prayers, and will provide updates as her condition improves."

"We again ask that you respect our wishes for privacy, and refrain from contacting us, our extended family, or Claire's friends and schoolmates, as we want to ensure that only accurate information about Claire is shared," the statement continued.

Arapahoe County Sheriff Grayson Robinson said when the shooter came upon her as he was looking for his intended target, Davis did not have a chance to escape.

"She is an innocent young lady, and she was an innocent victim of an evil act of violence," Robinson said. "She probably was simply in the wrong place at the wrong time."

As Davis remains in the hospital, her classmates have rallied around her.

A fellow senior, Chris Davis, who is not related to Claire Davis, started to collect donations on behalf of her family.

Chris Davis said in the last 48 hours he has already collected $4,000 and plans to make online donations possible on Monday. The senior decided to put together the fund as a way to cope with the violent events of the week.

"Me and a couple of my friends, we wanted to see how we could help ourselves and we thought we could help others by doing donations," Chris Davis told ABC News.

Although he said did not know the 17-year-old victim personally, he said he often saw her since her locker was near his.
